Richard, perhaps that is why my unit toasted. I was told by Pertronix that I did not need a ballast resistor. Of course I was also told by them that they did not make a unit for 235's and that the part # listed on a unit in my possesion did not exist. I did not opt for a replacement ignitor becuase I used it over two years, did not have the original receipt, and as I say my part # did not exist.
I wonder if my generator could produce 16 volts. I was told by a Petronix dealer who is no longer on the board that generators were weak, underpowered and a thing of the past.
